No rare coin or precious metals buyer or seller likes that uncomfortable feeling they get when working with a dealer they’re not sure about. The Professional Numismatists Guild has virtually eliminated that feeling for thousands of coin, paper money and precious metals collectors and investors throughout the U.S.

Founded in 1955, the PNG’s motto is Knowledge, Integrity, Responsibility. These are the key attributes you should look for when you’re choosing a rare coin dealer, paper money expert, or precious metals dealer. Every PNG member dealer has them, or they wouldn’t be part of our association.

The PNG logo has become the symbol of professionalism in the numismatic field. That’s why NGC – one of the largest coin grading services in the world – proudly displays the PNG logo on every one of its coin holders, more than a million annually. That’s testimony to the power of the PNG brand, and its membership.

Whether you’re looking to buy a few nice coins or investing a small fortune, why would you ever do business with any rare coin or precious metals dealer without PNG’s safeguards in place?

And for dealers whose reputation for integrity is everything,a PNG membership should be a given.

The Professional Numismatists Guild (PNG) is a nonprofit organization composed of many of the country's top rare coin and paper money experts who undergo a background check, must adhere to a strict code of ethics in the buying and selling of numismatic items and who guarantee the authenticity of the numismatic merchandise they sell.

PNG Mission:

Ensuring integrity, instilling confidence, and promoting professionalism for the benefit of all numismatic collectors and professionals.
